Unrolled build for #142346

Rollup merge of #142346 - Shourya742:2025-06-11-add-tracing-import-to-execution-context, r=Kobzol

Add tracing import to execution context

In #141909, we missed adding the trace_cmd import in the execution context module. This PR fixes that. Additionally, we are updating the mingw-check-2 check command to include BOOTSTRAP_TRACING=1 to help ensure we don't miss such cases in future PRs.
